TEMP_AVG_INTRVL (temp_avg_intrvl):
Temperature data is averaged over this period. At the end of averaging period 
(ms) , averaging process starts again. 0x1 - 0xFF = Averaging data is read via 
TEMPDIMM STATUSREGISTER (Byte 1/2) as well as used for generating 
hysteresis based interrupts.
00 = Instantaneous Data (not averaged) is read via TEMPDIMM 
STATUSREGISTER (Byte 1/2) as well as used for generating hysteresis based 
interrupts.
Note: Cpu does not support temp averaging.

Initiate 2X refresh on TEMPLO (ev_2x_ref_templo_en):
Initiate 2X refresh on TEMPLO
DIMM with extended temperature range capability will need double refresh rate 
in order to avoid data lost when DIMM temperature is above 85C but below 
95C.
Warning: If the 2x refresh is disable with extended temperature range DIMM 
configuration, system cooling and power thermal throttling scheme must 
guarantee the DIMM temperature will not exceed 85C.
